The following description was taken from FORS: An industry led response to environmental and safety concerns

Launched by Transport for London (TfL) in 2008, the Fleet Operator Recognition Scheme (FORS) is designed to improve commercial vehicle fleet standards, and safety is a fundamental aspect of the initiative. Indeed some parallels can be made between the proposed equipment required under the new ‘Safer Lorry Scheme’ and the safety features that must be added to vehicle fleets in order to attain FORS bronze accreditation. These include fitting side under-run guards to protect cyclists from being dragged under the wheels of a vehicle in the event of a collision, as well as Class VI mirrors that give the driver a better view around his/her vehicle.
